Dual Output
Description
Low cost, low profi le, open-frame 1W SMD isolated DC/DC dual output converters. The R1DX operates
from 5V and offers ±5, ±9, ±12 or ±15 dual outputs. There is no minimum load requirement and the
quiescent consumption is less than 150mW. Standard isolation is 1kVDC/1s and a /H version with
3kVDC/1s is available. The operating temperature is from -40°C up to +95°C without derating. The
pin-out is industry standard and compatible with the R1D series, but at half the height. The converters
are fully certifi ed to IEC/EN/UL62368 and IEC/EN/UL60950 and are 10/10 RoHS-conform. Class A
EMC conformity requires only an input capacitor and a simple low cost LC fi lter is all that is needed for
Class B EMC.
